Step 3 — Locate Unit
should be considered when choosing a location for a WSHP:
• Units are for indoor use only.
• Locate in areas where ambient temperatures are between
39 F and 102 F and relative humidity is no greater than
75%.
• Provide sufficient space for water, electrical and duct
connections.
• Locate unit in an area that allows easy access and removal
of filter and access panels.
• Allow enough space for service personnel to perform
maintenance.
• Return air must be able to freely enter the space if unit needs
to be installed in a confined area such as a closet.
NOTE: Correct placement of the horizontal unit can play an
important part in minimizing sound problems. Since
ductwork is normally applied to these units, the unit can be
placed so that the principal sound emission is outside the oc-
cupied space in sound-critical applications. A fire damper
may be required by the local code if a fire wall is penetrated.

— The following guidelines
FIELD CONVERSION OF DISCHARGE AIR — The dis-
charge air of the 50PSH horizontal units can be converted
between side and back discharge in the field. The conversion
process is the same for right and left return configurations. See
Fig. 7 and 8.
NOTE: It is not possible to convert return air between left or
right return models in the field due to refrigerant piping
changes.
